Sand mastic in West Yoke, done properly
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. If you have gaps where the frame meets the masonry and wind and rain getting in round a sash window, we can put it right, whatever the surface.
Somewhere as small as West Yoke, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

West Yoke questions
Do you cover smaller places like West Yoke?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Longfield station?
Yes. We work for letting agents and landlords as well as homeowners. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
How do I get a quote for sand mastic in West Yoke?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or send us an email with a short description of the job.
How long does sand mastic take to go off?
Not right away. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How long does sand mastic take?
That depends on the amount of work, but most jobs take a few hours per window, depending on the condition of the joints. We will give you a better idea when we quote.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What affects the quote in West Yoke
There’s no set price list, because no two jobs are the same. The quote depends on:
- The size of the job
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- Roughly how big the job is
- The type of property
- If someone has resealed it before
- A few photos by email, if you can
We quote each job on its own. Simply ring 0345 464 0079 or drop us an email and describe the job, and photos are welcome.
The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for a single window, longer for several. For a village or hamlet like West Yoke, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work
- Clear the area around the work
How to get a quote
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or drop us an email.

What else we do in West Yoke
Windows and doors in West Yoke
Historic houses like Lullingstone Castle (about 4.4 miles west) are a reminder that the area around West Yoke has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Parish Church of Saint Peter and Saint Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Longfield station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Landlord and commercial work in West Yoke
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Why deal with it now?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Older cottages and farmhouses around West Yoke can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

Common problems we fix in West Yoke
Timber swells and shrinks with the weather. The movement cracks the mastic little by little.
Look out for these signs:
- Mastic that needs renewing before redecorating
- Patchy fillers round a sash window
- Failed mastic on an exposed elevation
- Gaps between timber frames and stone or brick
For site and facilities teams at buildings such as New Ash Green Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Check with your local planning authority if your home is listed
- Ask us before painting near the mastic
- Renew mastic before redecorating the windows
- Avoid heavy scraping on the mastic joint
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
